求下列函數的導數y=2xsin(2x+5)

求下列函數的導數y=2xsin(2x+5)



y=2xsin(2x+5)
y'=2(x)'sin(2x+5)+2x[sin(2x+5)]'(2x+5)'
=2sin(2x+5)+2xcos(2x+5)×2
=2sin(2x+5)+4xcos(2x+5)



求函數y=2xsin(2x+5)的導數,


y'=2x'*sin(2x+5)+2x*[sin(2x+5)]'
=2sin(2x+5)+2x*cos(2x+5)*(2x+5)'
=2sin(2x+5)+4xcos(2x+5)



求y=2xsin(2x+5)的導


y'=(2x)'sin(2x+5)+(2x)[sin(2x+5)]'
=2sin(2x+5)+4xcos(2x+5)
